I have a backup stratum server operating on stratum+tcp://stratum2.bitparking.com:3333. If the main stratum server fails this one should continue operating. It's not a complete failover as it still relies on some features on the main server but will work fine for the types of stratum crashes that occurred recently. You can also pick the stratum server that provides the best latency for your miner. I'll continue working on a solution that works in the case of the main server completely failing.

I installed some monitoring on the pool hash rate to ping my phone if it dropped low and it triggered this morning. I was able to see the reason for the recent crashes and have fixed the issue. Pool had about 5 minutes downtime. I'll continue to monitor.

I've tried stratum2.bitparking.com, and initially it looked as if everything runs perfectly. Normal hashrate, zero stales. After a while I noticed that the balance doesn't match the number of accepted shares. I stopped everything and started a controlled test session:

I never experienced anything like this while mining at mmpool.bitparking.com.Seems there is a cache problem. After a while that cache is being cleared. Where have the missing shares gone?

The backup server does cache shares for a short time and this will always result in the website and stats being a number of shares behind. These are always submitted though. If you were to stop mining for a few minutes it'd catch up. Just in case though I've disabled the advertising of the backup server while I investigate to see if there are any issues.

There were some server restarts today to try and track down the issue causing the stratum server crash that has been occurring on the mornings. Hopefully I've done the last of these just now to resolve the issue.

At some point I plan to add support for notifying miners if their miner's stop mining. I'm open to suggestions on how best to handle the notification trigger. For my own server down notifications I'm using Pushover to send notifications to my phone. As a stopgap until I've implemented something for miners, if you'd like to receive pushover notifications if you're miner hash rate drops you can bitmessage me at BM-BbgTgGa6LX3yYqwJSwdwrzysvfWjM2u6 (or post here if you don't mind it being public, or PM me, or email the bitparking admin address) with your account name, your pushover user key and the hash rate minimum you want to receive a notification and I'll set a notification up for you.

This sounds awesome. Thank you for this offer! However, I'm curious if we decide to shutdown or mine a more profitable coin for a day or two, how would we be able to turn the notifications off?

Once you have it setup where we can change the hash rate minimum on the user end (add it as an input on our account page?), I wouldn't want to be locked in. Otherwise, my phone would be blowing up if I decide to mine PPC for the day or something, heh.

Good point, that would be annoying. Best to wait till I have an interface set up allowing you to set and edit the alerts.

Ya, for now, I had a friend write a Windows service to screen scape the site and send me an e-mail, but I can turn it on or off

Would definitely be easier if it is integrated into the site! Awesome stuff doublec!
